The Leaning Tower of Pisa is a free-standing bell tower of the Cathedral of Pisa. The tower is well known for its tilted to one side position. So why the tower leans? The tower was built unsuitable for the ground; it is only 6 ft above sea level and it’s built on a riverbed. While the underground layer is made up of clay and sand, over time, the weight of the tower tend to compressed the soil. That’s why the tower has sunk more in some places than the others.
